The superstar musician and his partner David Furnish first became parents to son Zachary on Christmas Day in 2010. Since then Elton has spoken of the joys of fatherhood and said of his son that "I haven't loved a human being more than him, ever."

Life with Zachary appears to have had a great effect on the pair, to the extent that they are considering having another child. Elton says that "When it's time, we probably will. I'm now the happiest I've ever been,"

Although it's on the agenda, the new addition to the family may not be coming just yet. Elton, 65, says "While I'm feeling good, I'm going to keep working," but "When Zachary goes to school, that's another different thing."

Keen to be an active parent Elton has said "I want to take him to school and I want to pick him up. I don't want to miss that part of his childhood."
